[Rd] R, AIX 64-bit builds - trying to understand root cause for message: "Error: Line starting 'Package: tools ...' is malformed!"

[Michael Felt]

This seems to be a problem that goes back a long time - and I hope 
someone who understands what tre is suppossed to be doing will look at this.

A short history of other people who have reported on this on different 
versions of AIX. I shall only add that I get the same results on AIX 5.3 
TL7, AIX 6.1 TL9 and AIX 7.1 TL3.

Basically, with settings that work for AIX and 32-bit - the only changes 
being
-maix32 becomes -maix64
and
export OBJECT_MODE=32 becomes export OBJECT_MODE=64

Then to shorten the 'make' bla bla, first run just make, then

cd src/library/tools
make -s sysdata

minutes ago)

To that, to get debug data, I have

* added -DTRE_DUGUG to src/extra/tre/Makefile # ALL_CFLAGS = 
$(ALL_CFLAGS_LO) -DTRE_DEBUG
* rm src/extra/tre/tre-match-parallel.o
* find . -name \*.so -exec rm {} \;
* make
* cd src/library/tools
* make -s sysdata

Attached are the two script files of the screen output. The 32-bit one 
is more verbose - and contains magically lines such as:
    found match 3037fd14 (while "found" does not occur in the 64-bit output)

Hope this brings us (or me), closer to a resolution to an old concern.

And, best wishes for the new year!
